The quality of some of the POC stuff I've seen has been shocking (without even taking into account the prices). Let me be the first to recommend the standard Troy Lee XC or Air, depending on how minimal you want them.

My two favourite pairs of gloves at the mo are my O'Neil Jump gloves (I think they're MX gloves, but the palm in thin and they're holding up really well) and my One Industries Zero glove (very basic with a thin palm...their stuff does come up big though so I'm wearing a size smaller nan I would normally).
